Default Why are revlimiters uneven?

On cars? Yes. Cutting the engine abruptly when you hit the red line
wouldn't be good so they simulate ignition breakup to give you a hint.


But at that point you've already gone over the peak of the power
curve. I'd just make it drop the curve more quickly so it can never
go too fast. The driver would still feel the lack of power.


Engines that run stochiometric have to be all or nothing. Diesel are
smoothly limited. It ought to be possible to smooth limit stratified
petrol but I don't know from experience because mine just shifts up and
keeps going.


My car is an automatic so that is what it does. I never tried putting it
in first or second to see what it does when it hits the limiter.

Two of my bikes have carburetors so manipulating injectors isn't an
option. I haven't hit the limiter on the other bike and just shift at
10000.
